Special Issue Information

Dear Colleagues,  

Motivated by the need to depart from fossil fuel-based electricity, photovoltaic (PV) power generation continues to attract attention from governments, industry, and academia. As the cost of solar panel manufacturing decreases, PV power generation has become competitive with other forms of renewable energy, and is being massively deployed. In this context, this Special Issue will publish original research on various aspects of power converters as enabling technology for efficient utilization of PV power generation systems.

Topics of interest include, but are not limited to, the following:

  • DC-DC converter topologies for PV applications;
  • Integrated PV cell-converter architectures;
  • Circuital models of PV arrays;
  • Maximum power point tracking algorithms;
  • Inverter topologies for PV applications;
  • Inverter modulation and control for ancillary services (e.g., power quality)
  • Ride through and various grid support algorithms during faults (e.g., transient stability enhancement)
  • Integrated PV power plants plus storage;
  • PV power plants for electric vehicle charging;
  • Artificial intelligence for control and optimization of PV systems;

This paper proposes two improved cascaded H-bridge (ICHB) multilevel inverters that feature voltage-boosting capability. The conventional H-bridge with a front-end dc–dc boost converter was restructured for single-stage operation. The developed three-level topology not only saves one power switch but also exhibits lower voltage stress across its capacitor. Extension to five-level generation was also introduced by merely adding two power switches and one capacitor. The final five-level topology outperforms the classical cascaded H-bridge (CHB) multilevel inverter with a significant reduction in the power switch count, with a 42% and 50% reduction in both the isolated dc source and inductor counts. The power efficiency was also improved without compromising the modularity feature of the classical CHB multilevel inverter. The operation and theoretical analysis of the proposed topologies were validated via simulations and experimental tests. Full article
